' 9 Claims.

This invention relates to life raft launching devices and it has for itsobject, among others, to provide a device that is rigid and secure, butwhich quickly and surely launches a life raft into the sea from the deckof a boat by a simple manual control. Y

With the foregoing and other objects in view, the invention resides inthe novel arrangement and combination of parts and in the details ofconstruction hereinafter described and claimed, it being understood thatchanges in the precise embodiment of the invention herein disclosed maybe made within the scope of What is claimed without departing from thespirit of the invention.

A practical embodiment of the invention is illustrated in theaccompanying drawings, where- Figure 1 is a side view of the invention.

Figure 2 is an enlarged detail of the releasing device.

Figure 3 is a rear elevation of Figure 1.

Figure 4 is an enlarged detail of releasing device (rear elevation).

Figure 5 is a plan view of Figure 1.

Figure 6 is an enlarged top detail of the releasing device. 1

Referring to Figures 1 and 3, the life raft support and launching deviceis preferably mounted on the deck A of a ship near one side thereof. Thebottom of the device may be formed of two opposed L bars I and laconnected at the rear ends by a cross L bar II, at the front by a crossL bar I2 and'an intermediate cross L bar I3 and such diagonal bracer(not shown) as devised for strength and rigidity, and may rest on thedeck A. The parts may be suitably secured together by welding, rivets,or bolts. Two vertical L bars I4 and I are rigidly secured to, near butsomewhat removed respectively from the opposite ends of the cross barII, and near to, but below the top, they are tied together, by an Lcross bar I6, and still nearer the top, by another L cross bar I1. Adiagonal brace I8 seats at .the bottomin the L cross bar I3 and issecured at the top to the up right L bar l4. Similarly a diagonal braceI9 also seats at the bottom in theL cross bar I3 and is secured at thetop to the upright L bar I5. Additional similarly secured diagonals and2| may be employed to enhance the strength and rigidity, as Well astransverse back diagonals 22 and 23, broken away centrally as shown inFigure.3. v

The top or raft support proper is mounted to swing from the full-lineposition to the dotted line position, as shown in Figure 1. The top isrectangular in form and comprises two opposed side L bars 24 and 25, afront L bar 26 anda rear L bar 21. Four corner plates 28, 29, 30 and 3|,and two diagonals, 32 and 33, secured at the front to corner plates 28and 29 respectively and at the rear to top cross bar 21, both strengthenthe top and provide rests for a raft which is supported thereon. A shortL clip 34 on the side bar 24 mounts a bolt 35 extending transverselythrough the bar 24 and on which is pivotally mounted the lower end ofthe upright 36, the upper end of which is pivoted on the bolt 31transversely mounted in an L clip 38 secured to and dependent from theside bar 24. The upright 36 proper is a U-bar having plates 39 securedat each end by locking U-plates 40.

Diametrically opposed and mounted on the right side bar Illa by anotherbolt 4| and clip 42 is another pivotally mounted upright 43, similar toupright 36, pivoted at the upper end on the bolt 44 which extendslaterally from the top side bar 25 by means of an L-clip 45 dependingfrom the top side bar 25.

Towards the front a U-bar 46, similar in construction to the U-bar 36,but longer, is pivoted on the left side bar I0 by a bolt 41 and an Lclip 48 at its lower end, and at its upper end, by a bolt 49 and a clip50, the U-bar 46 is pivoted on the rear end of the top side bar 24,

Diametrically opposed is a U-bar 5|, similar in construction to theU-bar 46, pivoted on the right side bar Illa by a bolt 52 and an L.0111) 53 at its lower end, and at its upper end, by a bolt 54 and adepending clip 55.

Mounted on the bar 46 is a lateral stop plate 56 and on the bar 5| 2.similar but oppositely positioned stop plate 51 so positioned that whenthe top is released the bars 36 and 46 and 43 and 5| take the launchingposition shown in dotted lines in Figure 1.

Depending from the top front cross bar 26 near each end are depending Lplates 58 and 59 and pivoted respectively below thebar 26 to the baseplates are two longer bars 60 and 6| which rise aboverthe bar 26 and soprovide two retaining uprights at the front to hold the raft buttiltable to the downward positio shown in dotted lines in Figure 1. I v

A. cable 62 passes through holes in the bar 26 and over the front edgesof the plates 58 and 59, which may mount a retaining padding, tonormally hold the stop bars 60 and 6| in the upright position, andthe-ends are tied to a thimble 63. ;A turnbuckle 64 connects the thimble63 with a the rocker 61 at the rear and pivotally mounts two links 12and 13 which extend forward under the bar I! and are pivoted on oppositesides of a bar 14 on a pin '15. The bar 14 is weighted at the rear end16 and is pivoted centrally'on a bolt 71 secured in the plates 69 and10, and mounts under the bolt 11 a depending handle 18. Clips 19 mountedon the rear end of a raft v(not shown) may engage under the top of thetop rear cross bar 21. A pin (not shown) may be passed through holes 80in the bottoms of the. plates 69 and 10 to lock the handle 18 against.rearward motion, and so the entire tripping devices if desired..-

As shown in Figures 2 and .4, a swivel 8| mounted between plates 69 and.10 above the rocker 14 on a bolt 82 mounts a radial pin 83 whichengages a recessv 84 in the .top of the rocker 14, by which it issecured, in the locked position of the latch- 6,6,:againstmovement,andabout whichthe rear endof the hook 65 is locked. The rocker 14 maybeactuated also by a cable (not shown) depending from the front end, at.85; or/and a cable (notshown) may be secured at 86 to the bottom of thehandle 18. Moving, the rocker 14 by a. cable or the handle 18 lifts theweight 16, the. latch 66, and withdraws the pin .83 whereupon the. topmoves forward, and the locking uprights swing for-,

ward, until the raft is launched by gravity over the side of the deck A.
